Price drop alerts for any website
Amazon-only price trackers cover Amazon. Store apps cover their own store. Monitor Agent watches any product page you can link to — and instead of a diff, you get the answer: “Price dropped from $1,899 to $1,499.”
Refreshing a product page is a part-time job
You’ve bookmarked the page. You check it at lunch, again at night, and the price never moves — until the one week you stop checking. Single-store trackers only work where they work; browser extensions only run while your browser does. What you actually want is one sentence when the number changes, wherever the product lives.
How it works
Describe the deal you're waiting for
Paste nothing, install nothing — write what you want to know in plain English, including your target price if you have one.
Pick a schedule
Every 4 hours on Max, daily on Pro — or weekly if the purchase can wait. The checks run in the cloud whether your laptop is open or not.
Get the number, not a screenshot
When the price actually changes, the AI writes you the fact — old price, new price, and anything else you asked about — to email, push, or Telegram.
Prompts people use
- “Has the price of the Sony A7 IV body dropped below $2,000 on this page?”
- “Track the price of this mattress — tell me when any discount appears.”
- “Is this flight-deals page showing Kyiv–Lisbon under €150?”
- “Did this store start a sale on the standing desk I saved?”
Silence until the price moves
Monitor Agent compares every run against the last one and stays quiet when nothing meaningful changed — no “page updated” noise because a review count ticked up. One honest caveat: checks are every 4 hours at the fastest, so it’s built for real purchases — electronics, furniture, flights — not for outracing bots in flash sales measured in seconds.

Frequently asked questions
Does it work on any store?
Any publicly reachable product page — big marketplaces, small shops, airline deal pages. It doesn't require a supported-store list because the AI reads the page rather than plugging into an API. Pages behind a login are the one exception: Monitor Agent can't see those.
How fast will I know about a drop?
Within one check cycle: every 4 hours on Max ($19.99/mo, up to 2 monitors), daily on Pro ($9.99/mo). That's the right speed for considered purchases; for second-by-second flash-sale sniping, a browser-based checker running on your own machine is honestly a better fit.
Can I set a target price?
Yes — put it in the prompt: “tell me when it goes under $500.” The AI evaluates the condition, not just any change, so a $2 fluctuation won't ping you if you asked for a threshold.
How is this different from Amazon price-history trackers?
Those are excellent for Amazon price history — and Amazon only. Monitor Agent is store-agnostic and condition-aware, and it also covers the non-price parts of a purchase: “back in stock,” “new colorway,” “shipping to my country enabled.”
What does it cost?
Pro is $9.99/mo for 7 monitors (5-day free trial, no credit card). Max is $19.99/mo for 14 monitors with 4-hour checks. One monitor = one thing you're watching.
